APPARATUS FOR CHARGING GAS-RETORTS.

SPECIFICATION forming part of Letters Patent No. 522,705, dated July lO, 1894.

Application filed November 29,1890. Serial no; 373,054.. at model.)

To all whom it may concern:

Be it known that I, JOSIAH CLEMENT CHAND? for Charging Gas-Retorts, of which the following is a specification.

This invention relates to the charging of inclined gas retorts and to the construction and application thereto of apparatus for antomatically efiecting such charging, whereby the loss of gas and the rush of flame which now generally take place when the retorts are charged are prevented.

In carrying out my invention I apply to the charging end of the retort whatI call a charging receiver, which is advantageously made somewhat in the form of a hopper, and I provide two sets of gas-tight closing doors or valves whereby the communication between the charging receiver and the retort can be opened or closed as required.

To enable my invention to be fully understoodI will describe the same with reference to the accompanying drawings, in which Figure 1 is an elevation of my improved charging apparatus shown as mounted upon rails in order that it may be moved for charging several retorts. Fig. 2 is a side view of the same; and Fig. 3 is a plan. section of the said charging apparatus on the line w, m Fig. 2.

Similar letters of reference indicate correspending parts in the several figures.

handle d and at its lower end is shaped,for

of the retorts will frequently get out of align- Fig. 4 is a ment,owing to expansion and contraction, the said receiver is adapted to move transversely upon the said carriage, and for this purpose I provide it with axles or trunnions h, it carried on wheels 'i, 2' designed to run upon rails or guides j, j attached to the carriage f, horns j j being provided for preventing the turning of the receiver relatively to the carriage. As shown in the drawings the lower end of the receiver is at some distance above the retorts so that the latter will offer no obstruction to its movement upon the rails g, g. In order to move the said receiver so that its lower end will rest in the seat e of the retort being charged, I provide means for lowering and raising it, and I advantageously eifect this by eccentrically securing the axles or trunnions h, h to two disks 7c, 71; upon the ends of a shaft Zpassing through the receiver. It will be obvious that when the disks k, are moved from the positions shown in Figs. 1, 2 and 4, for instance, by means of a lever 071. secured to one of the axles it that the said receiver will be lowered. The shaft Z is surrounded by a tube Z, as shown,'in order to protect it and its bearings and also'to prevent the as cape of gas.

n, n are pins secured to the horns j j for preventing the lever m from being moved too far in either direction; and o is a removable pin adapted to be introduced into a hole in one of the horns j for preventing the lever from being moved while the receiver is being traversed along its rails.

9, 9, are doors within the receiver for temporarily supporting a charge, which doors are provided with elongated axles or pivots q, q having secured to them arms r, '2' designed, when the doors are in their closed positions, as shown in Fig. 4., to rest upon a lever s. This lever is pivoted to move in a lateral direction in such a manner that, when moved to the left, the arm r of the right hand door will be unsupported and so allow the said door to drop, and when moved to the right, the arm of the left hand door will be unsupported and so allow the said left hand door to drop to discharge the contents of the hopper or receiver, the action of the two doors being practically simultaneous. A hole 25 is formed in the lever between the ends of the arms r, 1* asshown in Fig. 3, so that when a pin u is introduced into the said hole, as shown in Fig. 1, thelever s is prevented from being moved.

The operation of charginga retort with my improved apparatus is as follows: The doors ceiver, and the lever s is moved, say, first to:

theleft and then to the right, the doors p, p

I then drop whereby the charge of coal fall's "flame issues therefrom, thereby into theretort, the valveb is then again closed and the doors 29, p are lifted as also is thereceiver; the. latter can then be again filled ready for the next charging operation.

It will be readily understood that owingto" the fact that there is nocommunication be-u tween the external air and the interior of the retort, during thetime of the charging, pra'c tically no gas escapes from theretort and no preventing inconvenience to the stokers. I In the foregoing description I have only reterred to the movable receiver; it is to'be understood,however,tthat in small gas making structures or plants a separate chargingra ceiver may be usedjwith each retort asprobably thecost of apfewextra receivers would be less than that of the carriage and the ing and lowering mechanism.

In cases where separate receivers are em- 1 ployed it is obvious-that the said receivers may be permanently connected to their torts.

Having now particularly described and asraiscertained the natureof my said invention and in what manner the same is to be I declare that What I claim is-' g 1. Inapparatus for charging inclined gas performed,

retorts, the combination of a vertical receiver Y having an air-tight cover, and within it and above its discharging mouth a pair of doors serving to temporarily support thecharge, a carriage on which such" receiver is mounted, and'a lever and cam whereby thereceivermay be lowered to connect itsdischarging month i withthe receiving mouth of the retort, all substantially as set forth.

2.
